Limits of the New Habitable Zone

Here are some limits of the new habitable zone (HZ) for main sequence stars (Table 1) from Kopparapu et al. (2013) for six parameters: distance from star (Table 2), stellar flux (Table 3), equilibrium temperature (Table 4), period (Table 5), transit probability (Table 6), and maximum transit duration (Table 7). The 'conservative habitable zone' is delimited by the 'moist greenhouse' and the 'maximum greenhouse' limits. The 'optimistic habitable zone' by the 'recent Venus' and 'early Mars' limits. All calculated values include minor updates to the HZ definition from the original paper (Kopparapu, personal communication).
